In the title compound, C21H20N4O2, the intramolecular C-H center dot center dot center dot O hydrogen-bonded benzodiazolone moieties are planar to within 0.017 (1) and 0.026 (1) angstrom, and are oriented at a dihedral angle of 57.35 (3)degrees. In the crystal, two sets of intermolecular C-H center dot center dot center dot O hydrogen bonds generate layers parallel to the be plane. The Hirshfeld surface analysis of the crystal structure indicates that the most important contributions for the crystal packing are from H center dot center dot center dot H (51.8%), H center dot center dot center dot C/C center dot center dot center dot H (30.7%) and H center dot center dot center dot O/O center dot center dot center dot H (11.2%) interactions.
